Light field cameras play an increasingly important
role in computer vision and optical metrology. However, due
to their complex design, their calibration is very difficult and
usually precisely adapted to the respective light field camera
type. We present a method that extracts a light field from
an arbitrary light field imaging system without knowing and
without modelling the internal optical elements. We calibrate
the camera using a generic calibration procedure, transform
the obtained set of rays into an equivalent light field representation
and finally, reconstruct a rectified light field from the
irregularly sampled data. Experimental results validate the
method and demonstrate that the geometrical structure of the
light field is preserved by an adequate rectification.
